¶ A general solidity of structure, as distinguished from the softness of the Alimentive and the resilience of the Thoracic, characterizes the Muscular. (See Chart 5) Poke your finger into a fat man's hand and though it makes a dent that dent puffs back quickly. Do the same to the Muscular and you will find a firmness and toughness of fiber that resists but stays there longer once the dent is made. Not So Malleable ¶ This little illustration is typical of the differences between these two natures throughout their entirety. Just as the fat man's face gives to your touch, _he_ will give in to you more easily than any other type; but he will go back to the same place sooner and more smoothly when your pressure is removed. [Illustration: 5 Muscular the worker] The Muscular does not mold so easily, is less suggestible, is less tractable than the Alimentive or Thoracic but is less likely to revert afterwards. Built on the Square ¶ "On the Square" is a figurative expression usually applying to a moral tendency. In this sense it is as often possessed by one type as another. But in a purely literal sense the Muscular is actually built on the square. His whole figure is a combination of squares. The Alimentive is built upon the circle, the Thoracic on the kite-shape but the pure Muscular always tends toward a squareness of outline. We repeat, he is no more "square" morally than any other type, so do not make the mistake of attributing any more of this virtue to him than to others. ¶ Each type has its own weaknesses and points of strength as differentiated from other types and these are responsible for most of the moral differences between people. No Type Superior Morally ¶ Since moral weakness comes from type weakness and since each type possesses about as many weaknesses as the others, it follows that no type is superior "morally" to any other and no type is morally inferior to any other. Type and Temptation ¶ Morality is mostly a matter of how much temptation you can withstand. Every individual in a civilized community is surrounded by temptations of some kind most of the time. He does not want to yield to any of them. Every man and woman does the best of which his particular type is capable under a given circumstance. Each individual resists many temptations for which we fail to give him credit. He yields only to those which make such a strong appeal to his type that he lacks the power of resistance. In other words, each person yields to the temptations that prey upon his particular weaknesses, and what his weaknesses are will depend upon his type. In the grip of these temptations he may commit anything from discourtesy to crime--according to the strength of the temptation plus his own leaning in that direction. On the other hand, certain "immoralities" which appeal strongly to some types have no attraction whatever for others and these latter get credit for a virtuousness that has cost them nothing.
